Some aspects of telecommunication system are now presented with reference to various apparatus and method.These apparatus and method will be come shown in the drawings by (being referred to as " element ") such as various square frame, module, parts, circuit, step, process, algorithms and be described in the following detailed description.These elements can use electronic hardware, computer software or both any combinations to realize.These elements are implemented as the design constraint that hardware or software depend on application-specific and applies over the whole system.

For example, " treatment system " comprising one or more processor can be used to realize any part of element or element or any combination of multiple element.The example of processor comprises microprocessor, microcontroller, digital signal processor (DSP), field programmable gate array (FPGA), programmable logic device (PLD), state machine, gate control logic, discrete hardware circuit and is configured to perform other the suitable hardware of the various functions run through described by present disclosure.One or more processors in treatment system can executive software.Software should broadly be interpreted as meaning instruction, instruction set, code, code segment, program code, program, subprogram, software module, application, software application, software kit, routine, subroutine, object, executable file, execution thread, process, function etc., and no matter its be called as software, firmware, middleware, microcode, hardware description language or other.

Therefore, in one or more, described function can realize in hardware, software, firmware or its any combination.If realized in software, then this function can be stored as one or more instruction or code or encodes on a computer-readable medium.Computer-readable medium comprises computer-readable storage medium.Storage medium can be can by any usable medium of computer access.Nonrestrictive as an example, this computer-readable medium can comprise RAM, ROM, EEPROM, CD-ROM or other optical disc memory apparatus, disk storage device or other magnetic storage apparatus, or may be used for carrying or file layout be instruction or data structure expectation program code and can by other medium any of computer access.As used herein, disk and CD comprise compact disk (CD), laser disk, optical disc, digital universal disc (DVD) and floppy disk, the wherein usual magnetically rendering data of disk, and cd-rom using laser optics ground rendering data.The combination of foregoing also should be included in the scope of computer-readable medium.

In LTE, paging can be asked between network with subscriber equipment (UE), set up Non-Access Stratum (NAS) signaling by Web vector graphic and is connected.When Internet Protocol (IP) grouping (such as, packet) is sent to UE from certain entity be associated with external network or equipment, IP grouping can arrive grouped data network gateway (PGW or P-GW).If because such as UE is in idle pulley, there is not the dedicated bearer for UE, then IP will be forwarded a packet to the gateway (SGW or S-GW) on default bearing by PGW.Once IP divides into groups, the SGW arrived on default bearing, SGW just can determine to need to create dedicated bearer so that IP grouping is sent to UE.SGW cushions this IP provisionally and divides into groups and transmit down link (DL) data adver message to mobile management entity (MME), so that this UE of paging and create dedicated bearer.

In addition, in response to DL data adver message, MME can pass through to all evolved node B (eNodeB or eNB) be associated with the finally known tracing area (TA) for UE (such as, eNB near the Last Known Location being positioned at UE) send paging request message, carry out this UE auxiliary and set up wireless heterogeneous networks (RRC) and connect.In response to receiving this paging request message, eNB can send paging to the community be included in TA by wave point, and the information of this TA provides in paging request message.The System Architecture Evolution of UE (SAE) Temporary Mobile Subscriber Identity (S-TMSI) can be normally used to carry out this UE of paging.Paging request message can also comprise UE identification index value, eNB for use in paging receiving request message calculates paging occasion, in this paging occasion, the current UE that may be in the idle condition using discontinuous reception (DRX) will connect its receiver to monitor beep-page message.

A large amount of unlicensed spectrum (it also can be called as TV white space (frequency spectrum such as, between television channel) or white space) is not used or is seldom used.This unlicensed spectrum can be useful for various types of radio communication, comprises, such as, be difficult to arrive part rural broadband deployment, provide in the market lacking service broadband access and machine to machine (M2M) communication.According to this, the use of unlicensed spectrum can provide extra bandwidth and strengthen the evolution of WiFi and other wireless access technology around capacity and function two aspect significantly.

In one aspect, the use of LTE in unlicensed spectrum can be called as " LTE-U ".In in another, use LTE or enhancement mode LTE, in an unlicensed spectrum adaptive LTE or enhancement mode LTE in an unlicensed spectrum, expand other operation any of LTE or enhancement mode LTE and/or the LTE carried out in unlicensed spectrum or enhancement mode LTE communication in an unlicensed spectrum and can be called as " LTE-U ".

Although eNB can attempt to communicate according to LTE-U and UE, but UE may not be configured to monitor or monitor the paging that may arrive in unlicensed spectrum, this is because, such as, network does not also inform that UE does like this, or in order to not waste resource and energy, the ability that UE monitors paging is restricted (such as, UE can not monitor all time slots in all frequencies always) or the scope of unlicensed spectrum very large, and/or similar reason.In in such, traditional LTE paging as described above can not use in LTE-U application.

According to each side presented, describe the mechanism of enhancing, whereby, in unlicensed spectrum, paging can be carried out to the UE according to LTE operation, such as, LTE-U can be used to carry out paging to UE.The each side presented can contribute to guaranteeing that UE can successfully determine when and where is monitored paging or monitors, and regardless of the unpredictability (owing to the one or more frequency spectrums in a large amount of unlicensed spectrum may use LTE) according to the communication of LTE-U, UE power and resource constraint and/or other factors.

According to first aspect, and access point or base station (such as, evolved node B, it also can be called as eNodeB or eNB) data mailing to UE can be received.These data can be quoted by the paging request message from mobile management entity (MME), or are included as a part for the paging request message from mobile management entity (MME).Such as, paging request message can comprise and to adjust with the system information at UE place or to change relevant data or information.In other words, paging request message can indicate access point or base station by data relay to UE for the one or more operation of adjustment at UE place or messaging parameter.ENB can attempt such as in unlicensed spectrum, to use LTE and UE to carry out communicate (such as, paging) according to LTE-U.UE can be associated with short mark, and this short mark can based on longer overall UE mark, and can be the position of the specific quantity of such as this longer overall UE mark.This longer overall UE mark can be such as unique MME mark (GUMMEI) in IMSI International Mobile Subscriber Identity (IMSI), Temporary Mobile Subscriber Identity (TMSI) and/or the whole world.

The short mark of UE can be known to network (such as, eNB and other network components) and UE.ENB can determine the time slot in the Master Information Block (MIB) of being broadcasted by eNB, and this time slot is corresponding with UE based on the short mark of such as UE.On the one hand, MIB can be system information block or comprise system information block, and this system information block can comprise multiple parameter for UE initial access network the most often sent.Such as, system information block can include but not limited to: dl system bandwidth, distribute to designator and the System Frame Number (SFN) that hybrid automatic repeat-request (HARQ) confirms the resource of signaling in the downlink.In these areas, SFN can identify the radio frames of the 10ms of the community of eNodeB.

In response to receiving the data mailing to UE, eNB can activate or be set in MIB through determining the position (bit) in time slot, then, this MIB broadcasts or sends signals to all UE in the community that is associated with eNB by eNB.In this aspect, UE can by determine or the position that is activated detected in the time slot through determining in broadcasted MIB determines when to monitor this paging or expects this paging.In addition, between the paging window phase that eNB can occur subsequently during paging occasion, paging is carried out to this UE.

In a first aspect, UE can be configured to the scheduled time (such as, periodically), based on particular event generation and/or in response to other trigger and enter idle condition.In this aspect, idle condition can make UE can reduce processing expenditure relative to active state.Such as, UE can enter idle condition by abandoning being connected with the RRC of eNB.According to this, RRC connection can indicate or correspond to active state.When in idle condition and reside in eNB's or the community that is associated with eNB on time, UE can periodically wake up (such as, active state is transformed into from idle condition) to monitor the time slot (such as, determined time slot) of the MIB sent by eNB.UE can know based on the short mark of the information provided by network and UE which time slot monitoring MIB.In other words, UE can determine which time slot that will monitor MIB for paging information based on short mark.Time slot may dynamically change, and according to this, UE may need continuously and determine (with redefining) its time slot that should monitor based on (such as) its short mark regularly.

Such as, network can provide its short mark information relevant to specific MIB time slot to UE.The position that UE can detect in monitored MIB time slot exists or is activated, and according to this, the position this be activated is identified as instruction paging instruction.Indicate based on this paging, UE can determine that the data mailing to UE are received at eNB place.In other words, paging instruction can indicate eNB to comprise the data be intended to for UE.Indicate based on this paging, UE can be configured to determine paging window, and between this paging window phase, this UE should monitor or expect and receive its data.Such as, UE can receive the information of automatic network, and such as, system information block (SIB), the short mark of UE is associated with paging window, paging channel and/or other information relevant with paging by it.

In these areas, UE can carry out receiving system information by the mode of one or more SIB, and each in this one or more SIB all can comprise one group of parameter relevant with function.Paging window can be determined based on the system information be such as included in this one or more SIB.According to this, UE can determine paging window with reference to such paging information when identifying paging instruction.Therefore, then UE can wake or be transformed into active state up to monitor paging (such as, with the form of sent message) between paging window phase from idle condition.In certain aspects, paging can be the instruction to the adjustment of UE reporting system information or renewal.Further, the connection request (such as, the calling of travelling carriage terminating) that paging can arrive to UE (such as, being in idle condition) notice.

According to second aspect, and be similar to first aspect, eNB can receive the data that mail to UE and eNB can attempt to communicate according to LTE-U and UE.ENB can be identified at the time slot (such as, determined time slot) be broadcast to by eNB in the MIB of all UE in the community that is associated with eNB, and wherein this time slot corresponds to the UE that data mail to.Be different from the communication on traditional LTE frequency spectrum, in the communication by unlicensed spectrum (such as, according to LTE-U) time slot in the MIB that is associated with particular UE of period can be acyclic (such as, occur with unequal or irregular interval) or periodically (such as, occur with interval that is equal or rule).Such as, not every T millisecond (ms) occurs once, and the time that this time slot often can be less than Tms occurs once or often occurs once more than the time of Tms; But this time slot still can on average occur once by every Tms, and wherein T can be positive numerical value.According to this, this time slot can relative to or to occur compared to the previous time slot in the slot range in MIB or mark is acyclic.ENB can activate or be set in the position in average every Tms appearance MIB time slot once, to indicate UE to monitor paging to receive its data.Then, eNB can broadcast this MIB according to LTE-U by air interface.

In second aspect, and be similar to first aspect, for various reasons, when residing on the community be associated with eNB, UE can enter idle condition.UE periodically can wake the time slot (such as, determined time slot) monitoring the MIB sent by eNB up.UE can be informed in based on the previous message being supplied to UE by network the time slot that in MIB, it should monitor.Such information can comprise system information, such as, and System Frame Number.In one aspect, although eNB communicates with UE in unlicensed spectrum, the particular time-slot that but will monitor may be constant, but the frequency of occurrences of this time slot can be dynamic and/or acyclic (such as, average every Tms occurs once by this time slot) or periodically (such as, this time slot will occur with Tms).

Such as, when the position that UE determines in time slot is set or is activated, activated position can be identified or additionally be defined as instruction to there is paging occasion k by UE.In other words, paging occasion can be determined based on activated position at least in part.Such as, paging occasion can be subframe, may exist at the upper paging-radio network temporary identifier (P-RNTI) beep-page message being carried out to addressing sent of physical downlink control channel (PDCCH) in this subframe.In this aspect, P-RNTI can be the fixed identifier being used to indicate the beep-page message on physical down link sharing channel (PDSCH) used on PDCCH.According to this, paging occasion k can be advertised to UE in MIB together with other network entity.Can determine paging occasion k based on equation kxT+x (k), wherein x (k) is for UE and the two known positive or negative pseudo random number of network entity (such as, eNB).By comprising x (k) at equation, UE and network entity can illustrate the paging occasion k of (accountfor) saltus step in time (hop) or hop (skip).Saltus step paging occasion is current is can be configured according to 3GPP technical standard TS36.304 and TS36.331 (full content of the two is merged in the form quoted at this) in LTE.

According to presented each side, the value of x (k) can be determined by such mode: the corresponding time slot monitored by UE can corresponding with the one in the subframe type being applicable to paging (such as, non-multicast broadcast single frequency network (MBSFN) subframe).According to this, UE can determine the value of k based on the System Frame Number sent in MIB (SFN).

In response to identifying and determining paging occasion k, UE can wake to monitor paging up during paging occasion k.

Although herein the first and second aspects are separately described, but it should be understood that, UE, eNB and/or other parts can be configured to individually, with another in combination and/or with another and other and paging or the relevant function of non-paging use this first and second aspect in combination.
